"Builders Notes" published on the USITT Web site February, 2003.

"Notes for Builders and Users," is a description of all the elements of the goniophotometer, detailed construction tips, complete setup and alignment procedures, suggested setup procedures for some typical lighting instruments, some recommended testing protocols, and a parts list with suppliers.

"Photographs" consists of eight photographs of the goniomoter and some of its parts. (4.8 MB PDF file)

"Drawings" is a reduced-size set of the fourteen working drawings and one power supply schematic. (2.1 MB PDF file)

"CAD Drawings" is a DWG file from which full-size working drawings can be plotted. This file is essential for those planning to build their own goniometer since it contains, on sheet number 14, the full-size drawings of the protractor scales. (Note: anyone who is not able to use the "CAD Drawings" file to plot the full-size protractor scales should contact David Rodger, TD&T editor, to make arrangements to purchase a printed copy of the scales.)
